CONTAINER FOR PRESSURE-FILTERS.

Specification of Letters Patent.

Patented Trane 11, 1907..

Application tiled April 14, 1906. Serial No. 311,650.

To all whom t may concern:

Be it knewnthat I, CHARLES W. MERRILL, a citizen of the United States, and a resident ot Lead, in the county of Lawrence, State of South Dakota, have invented new and Ause- 'ful Improvements in Containers for Pressure-Filters, oi' which the following is a specitication.

My invention relates to an limprovement in containers for ilse in .connection with apparattzs for separating mililterable material from a mixture oi ilterable and unfilterable material, and particularly to improvements in 'pres'srre iilteis in which the separation and treatment of sach material is effected, and is primarily intended to apply to that class of lilter press in which cleansing, preeipitating or other material is introduced through independent openings into the containers.

'Intwo applications for Letters Patent of the United States heretofore liled by me in the United States Patent Otl'ice, one being Serial No. 252,524 and the other being Serial llo. 304,722, I have described' and claimed filter presses of the type of those. above referred te, and the present invention relates to improvements in forms of containers for ilse .in connection with presses of the characgoter ol those described in the said applications.

In the aforesaid applications I have shown and described containers provided with one or more openings at a convenient point or points, preferably in the bottom, in, or near which a rotativepipe is placed provided with suitable nozzles or nipples through which a cleansing medium is introduced at varying angles and degrees through the openings into the contents of the container. The present invention embraces a container in which the saine efl'ect is produced by a variety of slightly different means.

The present invention consists in substituting for the rotative pipe and nozzles, passages in the container walls throtgh which the cleansing medium may be introduced in any desired direction cr directions, or in any desired quantities.

The invention will be best understood with 5o reerence to the accompanying three sheets of drawings, which show containers of the saine general type as those described and claimed as a part of the aforesaid applications embracing theaforesaid invention.

' In the drawings Figure 1 represents a vertical cross-sectien o'l one type of container embodying the present invention; Fig. 24 an elevation of a container embracing it in a slightly modiiied forni Fig. 3 a vertical crosssection of the same construction shown in Fig. 1, but provided, however, with' two outlet openings; Fig. 4 a vertical section of a different slightly modified form; Figs. 5 and 6, vertical sections of still different modifiy cations, showing the inlet openings along the sides and on the top of the container; Figs.

l7 and 8, vertical cross-sections 0T still fur-v clined in pairs toward each other; Fig. 10 a plan view of the openings shown in Fig. 9

Fig. 11 a plan' view of a'portion of the inner wall of the container showing a single row of openings g; Fig. 12 a similar plan view show,- ing two rows oi openings g in the surface, arrangedso as 'to be staggered with respect to each other. Fig. 13, a vertical section of a container similar to that shown in Fig. 1, except that thecontinuous washout channel Iis replaced by an opening in the bottoni of the container closed bya gate; Fig. 14, a vertical section of a container similar to that shown in Fig. 4, except that .the continuous channel'is replaced by an opening closed by a gate. Fig. 15, a vertical section of a contalner similar to that shown in Fig. 5, except that the continuous channel is replaced by two openings closed by gates.

Similar lettersl refer to similar parts throughout the several views.

In the present application the containers are shown adapted for use in what is known as the closed deliveryl type of filter press, as distinguished from the open delivery" t Ype, although I may use either type. As in the other applications above referred' to, a: is ythe frame of the container which may be square in cross-section or any other suitable shape, 0 is an opening' or inlet either in a ring 10 formed preferably in the bottom of the -container, or in the bottom of the container itself through which the semi-solid or the uni'ilterable material hereinafter called for convenience the untilterable component is removed from the containers, and which, in the former case, when a series of contain- IOC:

IlO

4o through the channel o.

ers is put together in a filter press, makes a continuous passage through thefpress which is closed at the ends in any convenient Inanner and can be arranged to discharge into any suitable receptacle. a is a corresponding inlet for treating the unlterable component .in place with liquids, vapors or gases and which,7 is preferably placed at either or vlboth upper corners of the container or at all four 1o corners as shown, and in like manner forms a continuous passage or passages whenthe containers are put together in the filter press. d is an inlet in a ring 13 formed on Ithe upper wall of the container through'which the i5 material to be filtered is introduced which inlet is of the same general character as the outlet'o and becomes'a continuous passage when the containers are put together within the filter press, and is provided with lthe 2cl ports 9 through which the material is introduced from thepassage d into the chamber,

the channels o and al may` be consolidated and one channel used for Aboth purposes..

The details of construclion above set forth 2 5 are applicahleito all containers of the dify ferent types hereinafter described.

In the construction of container embody ing the present invention and shown in Fig. i, g represents a series of openings which are 3o connected with passage 1 passing longitudinally along and within the bottom wall of the container and emerging from the channel 1c. In this construction the liquids,

vapors or gases or other washout medium,

enter through the channel 7c, pass into the channel 1', andI thence emerge vertically up? ,fthe openings g are arranged on either side thereof.

In Fig. 4, two channels c are provided oneoneither side of the container, and openings g emerge/therefrom'in the manner shown in 5o that figure.

In the construction shown in Fig. 5, two

channels 7c are shown one on either side, .and a channel r connected with each. Theopenings q emerge from the channels r in the side wallsof the container into the container as before, and in this Way the cleansing me dium is introduced cross-wise through the container.

- In the form of container shown in Fig. 6,l two channels k are shown on either side,

and the channels care carried up to the top .of the container and cleansing medium introduced through openings in Vthe top as well as in the sides. The same is true of the con- 6 5 struction shown in Fig. 7 with the addition that the opening r extends through the botltom of the container and the openings are provided in this portion of the container in the saine manner as in Fig. 1.

Fig. 8 shows a continuous opening r con, necting with two openings channels c and running entirely around the interior of thev container, and provided with inclined openings g for giving any desired angularity to the direction of the cleansing medium and in this case causing it to converge tiiward, the

center of the container.v i

The Figs. 9 and l0 show the vopeningsg in an inclined position so asto concentrate the two streams in the same direction and Figs. ll'and V1.2 show the openings in a continuous line along the periphery of the containerin the former or in two lines staggered with res ect to eachother in the latter.

n Ithe construction shown as Figs. 13,14v `and 15, the construction of the openings through which the washing out medium enters, is the same as that shown in Figs. 1, 4 and 5, but Athe continuous channeii o through which the Washoutis effected, is .replaced by an opening o in the bottom of the container, which opening is closed in each case by means of the gate 12 which may he operated in any convenient manner. inthe construction shown 1n Fig.,- 15, two suchA gates are used. These openings need not of necessity be in the same place, nor need their direction be necessarily parallel; on the contrary two ormore may be. inclined toward or away from each other in either ldirection and they may be inthe same orin arallel or in any other plane or planes. lI'h'eir disposition, direction, angularity and size, Amay vary from time to time as may. be found most suitable. Any number may be used in connection with any one container and they may be placed at the saine or yat a different angle and may be used .singly or-in pairs or in any desired numbersI or locations.

. When the containers are put together in the press, the channel .7c forms a continuous 'opening longitudinally through thef press,

and itterininates in an a propriete-opening in either of the press heads, and the cleansn ing medium is introduced into the/channel therefrom by suitable ipes or other devices. In all cases the was out medium enters through the channel 7c, passes into the.v chan- IIO nel r and thence emerges through the open.

ings g into the interior of the container, and passes out through the passageo. If necessary, one or4 more channels l: may, he employed, as well as one or more channelsg',

all arranged or disposed in any convenirnetV manner-or position. Any number: of. openings g maybe employed, as well as any nunk. ber o interior perimeter of the container can be. ro-

vided with these openings. .In practice it i s-.

found preferable to have .the bottom slope openings o and all or any portion ofthe toward the outlet or outlets, and to make the -openings g parallel and to extend them upward from the bottom.

rihe method of putting the containers to- 5 `gether and using them inapress is particularly described in the aforesaid applications, and need not he further described here, the same forms no part ot' tlie'prosent invention.
